Find things by name

Choose between a list, a map, and a set.

A list is useful when you want the first, second, and third item. Sometimes you want the price of an apple without caring where apples sit in a list. A map connects a key, such as a name, to a value. A set answers a different question: have we already collected this badge? Adding the same badge twice does not make two badges. These collection features are experimental; use the supplied compiler route and check your target before shipping.
